Environmental info needed

[Resee Billings <dmbillin@CALVIN.STEMNET.NF.CA>]

  I am looking for information on the environmental impact that a smelter
can have on the land, water and people. Also what standards or rules are
necessary to protect the above. Does anyone know a site  or have
information to help.
Thanks
